An absolute measure of the fat content in various organs is an important part of diagnostics in obesity and diabetes. Fat quantification using MR-imaging is a non-invasive technique which provides both quantitative and spatial information on fat accumulation. However, for absolute quantification, it is necessary to address the various sources of contrast in MR-imaging. This paper summarizes basic

We studied the commencement and finishing of the growing season using different air temperature indices, the surface albedo, the chlorophyll fluorescence (Fv/Fm) and the carbon dioxide (CO2) tropospheric concentration, together with eddy covariance measurements of CO2 flux. We used CO2 flux data from four boreal coniferous forest sites covering a wide latitudinal range, and CO2 concentration measu

At Mach number 3.4, visualisation experiments of flowover backward-facing step (BFS) with or without roughness band attached on upstream wall are carried out via traditional schlieren and newly developed nano-tracer-based planar laser scattering (NPLS). The time-averaged flow characteristic of the reattachment region and the instantaneous rich structures of the redeveloping boundary layer in the s

A small rectangular strip of fcc Cu, containing a through crack on the nanoscale and subjected to loading under displacement control, is simulated using molecular dynamics (MD). The geometry is highly constrained and chosen to mimic that of a thin film between two stiff layers. The Lennard Jones pair potential is used for the inter-atomic forces. The centrally placed crack-shaped void is created b

Breast cancer is the most common form of cancer in women. While the prognosis for breast cancer patients without local or distal dissemination is relatively favorable, the prognosis is considerably worse once distal metastasis has been established. It is therefore imperative to identify molecular targets and develop novel anti-metastatic therapies that will stop, reduce or delay the spread and gro

The article argues for a greater attention to be given to discursive approaches to the leadership of innovation through proposing a variant of Potter and Wetherell’s concept of interpretative repertoires. Drawing upon empirical material from a case study of managers engaged in R & D activities at a multimedia company, the study illustrates how the talk and thought of leadership reveals the con

Control of the material microstructure in terms of the grain size is a key component in tailoring material properties of metals and alloys and in creating functionally graded materials. To exert this control, reliable and efficient modeling and simulation of the recrystallization process whereby the grain size evolves is vital. The present contribution is a review paper, summarizing the current st

Background: Integration of second-generation (2G) bioethanol production with existing first-generation (1G) production may facilitate commercial production of ethanol from cellulosic material. Since 2G hydrolysates have a low sugar concentration and 1G streams often have to be diluted prior to fermentation, mixing of streams is beneficial. Improved ethanol concentrations in the 2G production proce

Although the frequency of extra-pair paternity (EPP) has been described for many species, the relative importance of the various contemporary and historical factors explaining EPP variation is still the subject of debate. In this study, we found 11 polymorphic microsatellite loci in the Savi's Warbler (Locustella luscinioides), and used eight loci to analyze the paternity of 392 nestlings belongin

Popular Abstract in Swedish Cerebral Pares (CP) är en övergripande benämning på ett rörelsehinder som orsakas av en skada som inträffat i en omogen hjärna. Graden av rörelsehinder varierar. Det föds cirka 200 barn årligen i Sverige med CP. Hög muskelspänning i kombination med muskelförsvagning och svårigheter att ändra ställning kan leda till att höften går ur led (höftledsluxation) och att ryggenAbstract Background: Children with cerebral palsy (CP) have an increased risk of scoliosis, contractures including windswept hip deformity (WS), and hip dislocation. In 1994, a follow-up program and registry for children and adolescents with CP (CPUP) was initiated in Sweden to allow the early detection and prevention of hip dislocations and other musculoskeletal deformities. Purpose: To analyze t

C3 and C5 convertases are central stages of the complement cascade since they converge the different initiation pathways, augment complement activation by an amplification loop and lead to a common terminal pathway resulting in the formation of the membrane attack complex. Several complement inhibitors attenuate convertase formation and/or accelerate dissociation of convertase complexes. Functiona

Popular Abstract in Swedish DNA i form av kromosomer finns i cellerna och innehåller information som styr flertalet av kroppens funktioner. Människor har vanligtvis 23 par kromosomer, där den ena kromosomen i ett par härstammar från personens mamma och den andra från dess pappa. DNA ser ut som en vriden stege där stegpinnarna består av nukleotidbaspar. I cancerceller kan det finnas bitar av kromIn human cells there are usually two copies of each chromosome, but in cancer cells abnormalities could exist. The differences consist of segments of chromosomes with an altered number of copies. There can be deletions as well as amplifications and the lengths of the segments can also vary. Localising the deviant regions is of great importance for increasing the knowledge of the disease. In this t

Objectives To perform fine mapping of the autoimmunity susceptibility gene BLK and identify functional variants involved in systemic lupus erythematosus (SLE). Methods Genotyping of 1163 European SLE patients and 1482 controls and imputation were performed covering the BLK gene with 158 single-nucleotide polymorphisms. Logistic regression analysis was done using PLINK and conditional analyses usin

BACKGROUND: Antimicrobial peptides (AMPs) are important actors in the innate immune system. One class of AMPs is the human β-defensins (HBDs), a group of small peptides with a broad spectrum of antimicrobial activities. Expression of HBDs is downregulated in different manifestations of allergic disease. In this study, we examine whether allergen-specific immunotherapy (ASIT) affects the nasal leve

Popular Abstract in Swedish För cirka 1,8 miljarder år sedan, medan Skandinaviens urberg var under uppbyggnad, kristalliserade en järnrik magma till ett mörkt bergartskomplex av bergarterna gabbro och diorit. Denna magma hade bildats genom delvis uppsmältning av manteln under den dåvarande kontinentkanten, transporterats flera tiotals kilometer uppåt genom sprickor i jordskorpan och på vägen upp dThe Kleva Ni-Cu sulphide deposit is situated within a gabbro-diorite intrusive complex in southeast Sweden. The basement north of the intrusive complex is dominated by 1.81–1.77 Ga granites of the Palaeoproterozoic Transscandinavian Igneous Belt (TIB). Slightly older (1.83–1.82 Ga) rocks of the Oskarshamn Jönköping Belt, which hosts numerous syngenetic and epigenetic base metal mineralisations, oc
